I don't have an answer for you, but I feel your pain. I have found the TPMS to be basically useless as well. Better to get out your handy dandy manual tire pressure gage and check it the old fashioned way.
By the bye - I recently acquired an AIRMOTO digital tire inflator. It's about the size of a flashlight, charges by USB, and pumps up your tire in about three minutes. I love it.
